What is the fuel economy of a 2003 Honda Accord? 

So does the fact that all 2003 Honda Accord models have a 17.1-gallon gas tank mean that they all also get the same

Fuel efficiency, like fuel capacity, is determined by a number of different factors, namely engine size and transmission. Each of the 2003 Accord’s three trim levels were available with either a 2.4-liter I-4 or 3.0-liter V-6 engine, but also with either a manual or automatic transmission. The four unique combinations of powertrain and transmission result in four unique fuel economy ratings—which means that a full tank of gas in any given interaction will offer a different total mileage range.

How to save on fuel costs in a Honda Accord

While the 2003 Honda Accord has the same fuel capacity across the board, opting for a model with a better fuel efficiency—namely an Accord with a 2.4-liter I4 engine and a 5-speed manual transmission—can earn you as much as an additional 85.5 miles of range on a single tank of gas. That being said, with fuel efficiency ratings of up to 26 mpg combined city/highway, the 2003 Accord is fairly fuel efficient for its age. 
In addition to opting for a more fuel efficient interaction of the 2003 Accord, the following tips and tricks can help you to keep your fuel consumption—and fuel costs—as low as possible: 
  • Keep up with maintenance. Practicing regular care and maintenance on your Accord will keep the sedan running as smoothly as possible for as long as possible, including in terms of its fuel efficiency. 
  • Drive carefully. Avoiding harsh acceleration and riding the brakes will help to keep your Accord’s fuel consumption as steady and as low as possible. 
  • Avoid idling, especially in cold weather. Idling engine’s consume fuel without actually taking you anywhere, so it’s best to avoid leaving your Accord to idle, even when trying to warm up the vehicle on winter mornings.
